Answer 2

10) AB*AE = CF*AD

16*8 = 10*AD

AD = 16*8/10

AD = 12.8 cm

11) AB = AC

  ∠C  = ∠B                   (Angles opposite to equal sides are equal)

In ΔABC,

∠A + ∠B + ∠C = 180°   (Angle sum property)

90° + ∠B + ∠B = 180°   (∠B = ∠C,∠A = 90°)

2∠B = 180°-90°

2∠B = 90°

∠B = 45°

⇒∠B = ∠C = 45°
